Title: Improvements in or relating to a machine for working, moulding and shaping dough
IPC: A21C3/00
Filed: 1930-11-04
Abstract: 366,917. Dough-working machines. SCHRÍDER, J. N., 29, Tijnjestraat, Leeuwarden, Holland. Nov. 4, 1930, No. 33145. Convention date, April 11. [Class 87 (ii).] In a machine for shaping a sheet of dough into scroll form whilst being carried along on a conveyer belt, the sides of the sheet of dough are folded inwardly by two positively driven conical members 9 provided with circumferential ribs or projections 11. A lump of dough is placed on the conveyer belt 4 at 5, Fig. 1, and is flattened under rolls 7, 8 before having its sides turned over by the members 9 so as to make a rectangular sheet after passing the rolls 12, 13. The front edge of this sheet is curled over by a drag or mat 14 comprising transverse metal slats mounted on fabric side-bands secured to a bar 17. The partially rolled sheet then passes to one or more devices 18 which continues the rolling and closes the seam and finally to a pivotally-mounted, gappedmember 31, which completes the rolling action. The device 18 comprises a rectangular frame 19, Fig. 4, mounted on a bar 20 and pressing members 22 mounted on arms 21 projecting from the sides of the frame. The member 19 is rotated through an angle by the roll of dough until the teeth in a gapped ring of teeth on a disc 27 engage the teeth on a constantly rotating disc 28 whereupon the members 19 are positively driven through about half a revolution. During this movement the members 22 are partially rotated by the engagement of an arm 24 with a guide 23 and press on the roll of dough as indicated in Fig. 4b. The first tooth 30, Fig. 6, in each row of teeth on the disc 27, is guided radially and is pressed outwardly by a spring 35 and the next few teeth are pointed in order to facilitate engagement with the teeth on the disc 28 as described in Specification 366,925, [Group XXIV]. Specification 366,924 also is referred to.

Abstract: 945,420. Transistor automatic gain control circuits. STANDARD TELEPHONES & CABLES Ltd. Sept. 15, 1961 [Dot. 21, 1960], No. 33188/61. Heading H3T. A transistor radio receiver includes a grounded emitter stage 7 with a variable resistor 10 connected between the collector supply and the base for adjusting the D.C. working point, lowpass and high-pass filters connected in parallel between the receiver detector 4 and the base of the transistor 7, and a current dependent resistive network 12, 13, 14 shunted by a capacitor 11 in the transistor emitter circuit. Received signals are detected by the diode 4, and fed to the low-pass filter 6 which filters out the modulation to provide the a.g.c. signal, and also to the high-pass filter comprising a manual volume control potentiometer 8 and capacitor 9 which passes the modulation. The outputs from both filters are applied to the base of the transistor 7, the operating point of which may be adjusted by resistor 10. Amplified a.g.c. is taken from the emitter circuit across the non- linear network 12, 13, 14 and is fed to the front end stages 1, 2 which are to be controlled. In order that the stages 1, 2 may be biased to zero emitter current before the gain of amplifier 7 is reduced, the emitters of these stages are connected to a bias source 15.

Patent GB-1270871-A (GB)
Title: Method and apparatus for patching veneer
IPC: B27G1/00
Filed: 1969-07-01
Abstract: 1,270,871. Patching veneer sheet. BLACK CLAWSON CO. 1 July, 1969 [17 July, 1968], No. 33278/69. Heading B5L. A method of patching a sheet of veneer comprises feeding the sheet along a predetermined path, sensing a defect within the sheet while it is moving along the path, cutting and removing a predetermined portion of the sheet containing the defect while the sheet is moving along the path to form an opening of predetermined configuration within the sheet, and inserting a patch within the opening while the sheet is moving along the path. Apparatus, Fig. 1, for carrying out the method includes drive rolls 48, 108 and 225 and cooperating rolls 38, 112, and 208 respectively for feeding the veneer sheet along a table 30, and a plurality of patching stations 35 arranged in groups which are disposed along the path of the sheet with the patching stations in each group laterally offset relative to those in the other group(s) so as to cover the whole area of the sheet. Each patching station includes cutter wheels 70 each of which is rotated on energization of a respective clutch 65, an air nozzle 125 controlled by a solenoid valve, and a magazine 135 containing patches. In operation of the apparatus the sheet is fed by rolls 38, 48 over a sensing device 255 which, when it senses a defect, causes the appropriate patching station to be operated. As a result the clutch 65 is energized to cause the wheel 70 to rotate through 180 degrees and cut a portion B, Fig. 4B, from the sheet. When the cut portion reaches the air nozzle 125 the valve thereof is operated so that the cut portion is blown into a shoot 244 and on to a conveyer 235 to leave a hole H, Fig. 4C, in the sheet. As the sheet advances an air cylinder 215 is energized to move a slide which removes the lowermost patch from the magazine and inserts it into the hole H. The patch is pressed into the hole by a solenoid operated plunger and by engagement with a spring blade as the sheet advances. The patch P, Fig. 4D, is a push fit in the hole but may be held therein by heat-sensitive adhesive which was originally applied to its edges and then activated after insertion.

Title: Rotary fuel pumps
IPC: F02M37/06
Filed: 1954-11-19
Abstract: 752,777. Rotary pumps. SCHAURTE, P. Nov. 19, 1954 [Nov. 20, 1953], No. 33597/54. Class 110(2) A rotary fuel pump of the flexible chamber type is formed on a distributer casing and rotated by the distributer shaft of an internal combustion engine. The lower part 3 of the distributer casing has a groove 6 which is covered by a diaphragm 7 which is progressively pressed into the groove 6 by balls 8 driven by a disc 18 which has an annular insert 20 of similar material to the diaphragm 7 and is rotated by the distributer shaft 1. The disc 18 is rotatably mounted on a bearing 15 and pressed by a spring 19 into contact with the balls 8. A cage 21 keeps the balls 8 in position and balances the centrifugal forces acting on them. A pin 9 draws the diaphragm 7 into the groove to close it at that point and the inlet and outlet ports are formed one on each side of the pin 9 (see Fig. 2, not shown). One or more apertures 32 are formed to facilitate escape of any fuel which may leak from the groove 6. A grease cap 23 may be provided for lubricating the shaft 1.
Patent GB-698402-A (GB)
Title: Improvements in and relating to recording apparatus
IPC: G11B15/16
Filed: 1948-12-31
Abstract: 698,402. Driving sound film, tape or wire. NIBLETT, E. H. Dec. 30, 1949 [Dec. 31, 1948], No. 33615/48. Class 40 (ii) [Also in Group XVI] In a recording apparatus in which the record is carried by a tape, web or ribbon drawn onto a rotating storage reel, a pair of members are adapted to engage the tape so that any interruption in at least that part of the tape so engaged will cause at least one of the members to move, and a pair of electrical contacts not in engagement with the tape are actuated by the movement of the tape-engaging member (or members), whereby, on interruption of the tape, the rotation of the storage reel is stopped. In one embodiment, Fig. 4, the tape 10 is guided over a fixed guide pulley 11 which has a recess 21 into which a pressure member 12 on an arm 13, pivoted at 14, is constrained to enter by a spring 15, but is prevented by the tape. When there is a break in the tape the arm 13 moves and thereby moves a contact arm 23 which meets a fixed contact, thereby completing an electrical circuit to short- or open-circuit, a solenoid associated with the recording apparatus to which the invention is applied (as described in Specification 698,401), and thus to stop the rotation of the reel on which the tape is being wound. The contacts may be inside a recess in the pulley 11 and operated by the member 12 when it enters the recess. A break in the tape may be purposely provided by a slot in the centre of its width. Instead of there being a separate contact area, the arm 13 may itself carry the moving contact. In another embodiment, Fig. 6, the tape 10 passes between pads 25 on fingers 24, which are secured to a bracket 28 and urged together by a spring. The bracket 28 is pivoted on an axle 33 and carries an arm 29 with a moving contact 30, a spring 32 tending to hold the parts so that the contact 30 presses on a fixed contact 31. When the tape 10 moves in the direction of the arrow the friction between it and the pads 25 pivots the finger 24 about the axle 23 and opens the contacts, and when there is a break in the tape the spring 32 closes the contacts. This arrangement can be combined with means, operated by the recording apparatus, for deflecting the spring fingers to allow the tape to be removed without breaking the solenoid circuit. Regarding this second embodiment, the Provisional Specification states that, owing to the comparatively large movement, the contacts 30, 31 may be dispensed with and the lever 29 may act as a mechanical trip. The Provisional Specification also discloses an arrangement in which the moving contact is also the pressure member, the fixed contact being the guide pulley. In this arrangement a tape may be used which ends in a length of metallic foil, by which means electrical contact is made and the tape stopped before it leaves its reel.

Abstract: 374,782. Safety razors. JULLIARD, M. E., 28, Avenue Victor-Emmanuel III., Paris. Dec. 4, 1931, No. 33690. [Class 30.] A thin safety razor blade, particularly a narrow one, 6, of a half-centimetre width, is held between clamping members which are flat in their middle part 2, and longitudinally curved at each end 3. To hold the blade more firmly, the ends may be curved on a less radius 'than if the entire shaving head were curved. The razor shown is of the kind having fixed upper and lower clamping jaws between which the continuous blade 6 is fed from a case 5. Wide blades of normal type may also be so curved, the resulting longitudinal tension improving their cutting qualities.

Title: Improvements relating to the distillation of coal and other solid carbonaceous substances
IPC: C10B7/14
Filed: 1936-06-06
Abstract: 481,584. Carbonizing - apparatus. JONES, F. W. SALISBURY-, and NISBET, R. June 6, 1936, No. 33996/35. [Class 55 (i)J Coal or the like is distilled at about 650‹ C. by being fed into containers which move by gravity through an externally heated retort under control of a lowering device which comprises supports moving along the path of the containers. The containers, after being charged, are passed through a gas-tight closure into the retort and removed through a similar closure for discharging purposes. The retort 3 is constructed of open-ended elements of oblong crosssection, for example 2 ft. by 6 in., and is supported by a footstep 4 and frame 1, and has a gas offtake 7, and an inlet 6 carrying the casing of an inlet valve 37. The containers 8 are charged from a hopper 54, a measuring hopper 55, and a hinged shoot 56, and enter a pocket 42 in the valve 37, rotation of which delivers the container into the retort inlet 6. A similar valve at the bottom of the retort delivers the container to an outlet opening 41. Each container 8 rests on the one below and is provided with a shoe 13 which rests on the upper ends of fittings 11 of the lower container, the containers resting against rubbing strips of the retort sides by rubbing strips 14. The containers are supported by arms 27 of endless chains 26 passing over sprocket wheels 25 in a casing 17, skid bars 31 supporting the chains against the pressure of the arms. The supporting device co-operates with an elevating endless chain conveyer 47 which runs over sprocket wheels 46, 50 and has arms 48 similar to the arms 27 which engage the containers by their trunnions 15. The containers are discharged by being inverted over a discharging hopper 49. The elevator chains 47 are driven at a higher speed than the chains 26 and carry the empty conveyers upwards, in a path excluded from the heat of the retort flues, to guides 45 leading to the charging opening 40.

Abstract: 622,139. Cramps. ROBERTSHAW, E. G. F. Nov. 18, 1946, No. 34075. [Class 61(ii)] [Also in Group XXIV] Operating mechanism for the sliding jaw 19 of a joiner's cramp comprises an operating lever 25 pivoted at 23 to the fixed jaw 21 and coupled by a link 27 to a sliding pawl 30 co-operating with teeth on a rack bar 31 secured to the sliding bar 20 of jaw 19. Also mounted on the pivot 23 is a handle 24 having a certain amount of rotary and lateral'movement relative to the lever 25 allowed for by a pawl 33 pivoted at 32 to said lever and having an end 34 cranked around the handle. The pawl 33 also has a locking tooth 43 co-operating with teeth on a quadrant 44 and a pair of laterally disposed cam surfaces 35, 36 adapted to co-operate with a spring-loaded latch 39 pivoted at 37 on the handle 24. With the parts in the positions shcwn, the end 38 of latch 39 is engaging the cam surface 36 of pawl 33 to hold it out of engagement with the quadrant 44 so that the handle 24 may be rotated freely to operate the lever 25 by engagement with the pivot pin 32 and so operate the jaw actuating pawl 30. On the required movement being completed the handle 24 is moved laterally to disengage the latch 39 from the cam surface 36 and engage it with the cam surface 35 under the tension of its spring, which forces the pawl 33 with its tooth 43 into engagement with the locking quadrant 44. For unlocking, the handle 24 is moved laterally in the opposite direction, the end 38 of the latch 39 being raised to engage cam surface 36 again, by a cam surface 41 on a cranked arm 42 on the lever 25 engaging the latch, and so lifting the pawl 33 from engagement with the quadrant 44.

Title: Photographic multilayer material for colour photographic purposes
IPC: G03C7/28
Filed: 1937-12-09
Abstract: 507,418. Colour photography. CASPAR, B. Dec. 9, 1937, No. 34083. [Class 98 (ii)] Multi-layer material comprises at least one sensitive layer which is coloured with a dyestuff which transmits the light to which the layer is sensitized and absorbs the light to which the layer above it is sensitive and which is capable of being bleached by the silver image, the layer containing an additional dyestuff of the same colour which is, however, totally removed by the treating solutions which are harmless to the image-forming dye. In an alternative, the additional dyestuff is one of similar properties to the image-forming dyestuff and is destroyed in the presence of finely divided silver. The concentration of the first dye is sufficient for colouring the most intensely coloured parts of the image, whilst the concentrations of both dyes are together sufficient to absorb all the light to which the front layer is sensitive. The auxiliary dyestuff may be in a separate colloid layer. In one example, a green or red sensitized emulsion dyed by a mixture of Xylenewalkgelb and 4 : 4<1>-methenylbis-[1-(p-sulpho-phenyl)-3-methyl-pyrazolone-5] is arranged between a blue sensitive silver halide emulsion layer dyed magenta with a salt of Tuchechtbrillantrot and a blue sensitive silver halide layer dyed blue - green with Pontamine Sky Blue 5BX. The,support may be adjacent one of the outer layers or between the layers. The dyestuff is decolourized by an alkaline developer or by sulphite or bisulphite compounds, and the dyestuff images are produced as in Specification 415,040. In a second example, a support is coated with a silver halide layer coloured blue-green with a quinolinium salt of Pontamine Sky Blue 5BX and sensitized with Cryptocyanine for infrared light, and containing also a destructible dyestuff obtained from 1-(p-sulphophenyl)-3- methyl-pyrazolone-5 and glutaconic-dialdehydedianilide. The destructible dyestuff may be in a separate thin gelatine layer. An emulsion layer sensitized to rod with pinacyanol and coloured magenta with a quinolinium salt of Tuchechtbrillantrot 2B is coated directly on the blue-green layers. The magenta layer or a separate layer lying above it contains a red dyestuff which may be the diphenyl guanidine salt of the sulphonic acid of methenyl-bisoxythionaphthene. A yellow coloured layer sensitized to green is coated above this layer. The auxiliary layers may be light-sensitive and the dyestuffs therein destroyed after a diffuse illumination which allows a separate exposure of the auxiliary layers. Specifications 408,991 and 506,385 are referred to.

Title: Manufacture of benzoic acid
IPC: C07C51/265
Filed: 1961-09-22
Abstract: Benzoic acid is made by a continuous process which comprises reacting a monoalkylbenzene with molecular oxygen in an oxidation zone in the presence of liquid benzoic acid and a heavy metal oxidation catalyst at a temperature above the oxidation potential threshold temperature of the monoalkylbenzene, removing heat of reaction by indirect heat exchange between reaction mixture and a cooling medium, withdrawing liquid reaction mixture from the oxidation zone, recycling the major portion of the withdrawn liquid reaction mixture to the oxidation zone, and removing a minor portion of the withdrawn reaction mixture for the recovery of benzoic acid therefrom.  The oxidation may be effected adiabatically or isothermally. In one adiabatic method, a portion of the resulting reaction liquid, mainly benzoic acid, is withdrawn from the oxidation zone and passed through an external heat removal loop and the cooled liquid reactor effluent is returned to the oxidation zone.  A slip stream of the liquid in the external loop is withdrawn, preferably before the heat removal, and processed to recover benzoic acid.  Make-up monoalkyl benzene is preferably added to the cooled recycled stream. In another embodiment, an isothermal oxidation zone is in indirect heat exchange relationship with a cooling medium for heat removal, for example by using a tubular coil or bundle of tubes or elongated cylinder surrounded by the cooling medium, preferably water.  The effluent is passed to a gas-liquid separator, the liquid is withdrawn from the separator, a major portion being recycled with make-up monoalkylbenzene to the oxidation zone, and a minor portion being processed to recover benzoic acid. Suitable forms of apparatus for the oxidation of monoalkylbenzene and the recovery of benzoic acid are described.  The oxidation temperature is preferably 300-400 DEG  C. manganese and/or cobalt compounds are preferred as the heavy metal catalysts but nickel, chomium, vanadium, molybdenum, tungsten, tin and cerium can be used. The catalyst preferably contains bromine in ionic, elemental or covalent combined form. Detailed examples are given.  Specification 1,008,192 is referred to.
